E-mail: [email protected]; [email protected] Abstract In order to evaluate the five species groups of Chinese Amolops based on morphological characteristics, and to clarify the phylogenetic position of the concave-eared torrent frog Amolops tormotus, we investigated the phylogeny of Amolops by maximum parsimony, Bayesian Inference, and maximum likelihood methods using two mitochondrial DNA fragments (12S rRNA, 16S rRNA). Our results supported a sister group relationship of Amolops ricketti and Amolops hainanensis. However, the grouping of Amolops mantzorum and Amolops monticola needs to be resolved with more data. Amolops tormotus was nested in genus Odorrana. Thus, recognition of the A. tormotus group is unwarranted and A. tormotus should be referred to genus Odorrana as O. tormota. This species is the sister group of O. nasica plus O. versabilis. The new classification implies that the genus Wurana is to be considered as junior subjective synonym of Odorrana. Key words: phylogeny, mitochondrial DNA, Amolops, Amolops tormotus, Odorrana tormota Introduction Among the Southeast Asian ranids, Amolops Cope, 1865 (sensu lato: Dubois, 1992) is characterized by the presence of an abdominal sucker in tadpoles and its peculiar occurrence in torrents. Since the taxonomy of this group was questioned (Inger, 1966), significant advances have been achieved in the past few years. Yang (1991a) recognized three distinct genera including Amolops Cope, 1865, Huia Yang, 1991, and Mer- istogenys Yang, 1991. Later, Yang (1991b) united these genera into the subfamily Amolopinae within the Ranidae. However, Dubois (1992) did not accept these taxonomic schemes and merely relegated Yang’s three genera as subgenera within his genus Amolops, along with the subgenus Amo. In China, Jiang et al. (1997) added Pseudoamolops to the Amolopinae, with Rana sauteri as the type species. However, the monophyly of Amolops or Amolopinae was not independently verified using molecular data until very recently (e.g., Matsui et al., 2006; Ngo et al., 2006; Frost et al., 2006). Most species of Amolops sensu stricto, the type genus of Amolopinae (Yang, 1991b) or subgenus of Amol- ops sensu lato (Dubois, 1992), are distributed in China (Yang, 1991a; Frost et al., 2007). They are divided into five groups: A. tormotus, A. monticola, A. mantzorum, A. marmoratus and A. hainanensis groups (Fei et al., 2005). Matsui et al. (2006) and Ngo et al. (2006) studied some Chinese species of Amolops. However, data were lacking for the A. tormotus group. The concave-eared frog A. tormotus, initially classified as Rana tormotus by Wu (1977), has ultrasonic Accepted by M. Vences: 18 Jun. 2007; published: 23 Jul. 2007 49.

  • Local Population Differentiation and Phylogenetic

Genetic differentiation between populations of R. amurensis from Sakhalin and the Maritime Territory was found to be minimal. The resultant phylogenetic tree indicates monophyly of brown frogs and earliest divergence of R. amurensis among all the brown frogs studied. For this reason, separation of R. amurensis from the R. japonica group is suggested, but separation of the R. sauteri complex as a distinct ge- nus or subgenus Pseudorana is not supported.

From the phylogenetic trees obtained, we propose to include Rana zhengi in the brown frogs. Monophyly of the brown frogs was not unambiguously supported, but four well-supported clades (A, B, C, and D) always emerged, although relationships among them remained unresolved. Clade A contained brown frogs with 24 chromosomes and was split into two distinct subclades (Subclade A-1: R. chensinensis and R. huanrenensis; Subclade A-2: R. dybowskii). Polytomous relationships among populations of R. chensinensis and R. huanrenensis suggested the necessity of further taxonomic assessment.

Zoological Studies 42(1): 193-202. Sauter’s frog, Rana sauteri Boulenger, 1909 in the west-central part of the Central Mountain Range of Taiwan at eleva- tions of 300 to 2360 m showed obvious elevational clines in reproductive and life cycle traits. With an increase in elevation, the breeding season and the periods of calling, aggregation, and egg deposition of mature frogs shifted from fall and winter (Oct. to Dec.) to spring (May), while the breeding period decreased but the larval period increased. Also, adult females at high elevations were larger and produced smaller clutch sizes but larg- er eggs and tadpoles. The temperature experiment showed that low temperatures in winter at high elevations and high temperatures in summer at low elevations are the primary environmental factors that define the breed- ing success of the species. Rana sauteri has experienced long-term selection by environmental factors (e.g., temperature), resulting in populations at high elevations breeding in spring and populations at low elevations breeding in fall and winter to ensure that their tadpoles can grow and complete metamorphosis.

Information is provided on the ecology, habitat, reproduction, and geographical distribution of the species together with notes on the water chemistry of the collection site. A brief synopsis is given of the morphological differences between A. himalayanus and A. formosus, with which latter species A. himalayanus is often confused. A. himalayanus has been reported from seven localities in northern India and Nepal but, of these, only the original description of the taxon from Darjeeling was based on incontrovertible data. INTRODUCTION The 49 species of Cascade frogs belonging to the genus Amolops occur from Nepal and northern India to western and southern China and south to Malaysia (Frost, 2015). In Bhutan, A. mantzorum has been recorded at Choetenkora in Trashiyangtse District (Wangyal, 2013), A. marmoratus at Sershong in Sarpang District (Das & Palden, 2000), and A. cf. monticola at Ririchu in Wangdue Phodrang District (Wangyal & Gurung, 2012). Wangyal (2014) predicted the occurrence of A. himalayanus (and A. formosus) in Bhutan on the basis that the country was suitable for these two species both geographically and climatically.

Jowers, e-mail: [email protected] Manuscript received: 23 December 2019 Accepted: 21 July 2020 by Jörn Köhler Abstract. Tadpoles of the Asiatic torrent frog genus Amolops possess large abdominal suckers and a complex oral appa- ratus which allow them to adhere tightly to and also to move over wet rock surfaces, a morphology termed gastromyzo- phorous. Accounts of larval development, and overall sucker morphology and microstructure are patchy in this genus. Here, from a large sample (n = 90) of Amolops tadpoles collected from two sites in Nepal, we give a detailed description of the tadpoles’ external morphology, including pigment pattern variation, and their development from soon after hatch- ing to the approach of metamorphosis, including new features of their oral apparatus (tooth rows and labia). Using SEM, we describe ultrastructural details of the sucker’s surface, especially microvillated cells of the friction areas.

Biological Sciences Program, School of Distance Education, Universiti Sains Malaysia, 11800, Penang, Malaysia *E-mail: [email protected] ABSTRACT A brief study of the amphibian fauna of Bubu Permanent Forest Reserve, Perak, which constitutes the southernmost part of the Bintang Hijau Forest Reserve, was carried out from 18 to 21 December 2006 to determine the diversity and density estimate of amphibian species in the area. Field parties comprising seven persons searched and collected amphibians from a small stream, the Dal River, in Compartments 6 and 7 of the Bubu Permanent Forest Reserve, from 2000 hrs to 2300 hrs for three consecutive nights. A total of 79 individual frogs from 13 species in five families were recorded. The five most abundant species were Hyalarana nicobariensis, H. labialis, Pedostibes hosii, Phrynoides aspera and Amolops larutensis. Six other species were considered rare, namely, Limnonectes doriae, H. picturata, Odorrana hosii, Polypedates leucomystax and Rhacophorus bimaculatus. Preliminary analysis of the data showed that the estimated populations of H. nicobariensis, H. labialis and P. hosii are 23, 13 and 10 individuals per 100 meters of river length, respectively. Due to the brief nature of the study, and the small area covered, the number of species is considered relatively moderate. More than 95% of frogs collected are forest species that require clean and pollution-free habitats to survive.
